CHECK-HOOK.

TSPECIFICATION forming part of Letters Patent No. 650,567, dated May 29,1900.

Application filed June 27. 1899. Serial No. 722,066. No model-l To allwhom may concern.-

Be it known that I, OLIVER I. ROBERTS, a

citizen of the United States, residing at T0- males, in the county ofSan Francisco and State of California, have invented certain new anduseful Improvements in Checkre'in- Hooks; and I do hereby declare thefollowing to be afull, clear, and exact description of said invention,such as will enable others skilled in the art to which it most nearlyappertaius to make, use, and practice the same. This invention relatesto improvements in checkrein-hooks; and it consists in the novelarrangement and construction of the parts hereinafter set forth.

The object of the present invention is to provide a hook to receive theend of the checkrein which will be closed to lock the checkrein inposition, but which will not necessitate the drawing of the checkreinfartherback than the position in which it normally rests while beingplaced in the hook.

\Vith these objects in view the invention consists in the variousmatters hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of a checkrein-hookconstructed in accordance with this invention, the dotted lines beingused to indicate the end of the cheekrein and the loop with which it isprovided. Fig. 2 is a side elevation of the same, the hook being partlycut away to show the construction of the hinged portion of the bridgeand the latch for locking the same in position. The interrupted linesherein shown indicate the path of the end of the bridge in being placedin its normal position.

To facilitate the description of the invention, I will assign the letterA to the hook portion. The forward part of this hook is slightly curvedand is slotted at its upper end to receive the hinge-wing B of thebridge B,

said wing being pivoted between the side walls of said slot. The rearportion of the hook A is turned upward and extends beyond the height ofthe forward portion of the hook. The upper end of the rear portion isseparated to form a slot to receive the latch C, which is pivotedbetween the side walls of the slot by means of the pin 0. The latch 0when in position fits snugly between the side walls of the slot in whichit is contained and forms, in conjunction with the part of the hook A towhich it is applied, a continuous extension above the line of the closedhook or loop, as shown in Fig. 1. In this position it is maintained bythe flat spring D, the free end of which rests against the back of thelatch, while the fixed end is secured to the hook A. WVhen now theseparts, constructed and assembledfas h erein shown and described, areoperated, the bridge l3 is raised in position shown in Fig. 2 to receivethe end of the checkrein E. The bridge in being thrown upward is byreason of its being secured to the forward extension of the hook A alsothrown forward and rests in a position practically in line with theforward extension of the hook A. By reason of the bridge B being thusraised, as shown in Fig. 2, in line with the forward extension of thehook A the said bridge may be used as a lever to draw the rein and headback to the desired position, thus facilitating the operation of placingthe checkrein. When it is thrown down into its normal position, thebridge B spans across the upper part of the hook A, closing the same.

In falling into this position the small hooks like extension B strikesagainst the face of the latch C, and the rest for said extension B isformed with a raised shoulder A, which extends in front of the hook Bwhen the same is forced into the position shown in Fig. 1, and astherein shown in dotted lines. Immediately the hook B passes below thelatch O the said latch is thrown, by means of the spring D, over the topof the hook B the bottom of the latch O being shaped to conform to theupper surface of the hook B In the position as shown in Fig. 1 of thedrawings it is impossible to withdraw the hook 13 from the engagementwith the shoulder A until the latch C is raised or withdrawn from on topof the said hook B Therefore when in the operation of securing thecheckrein the bridge B is thrown down into the closed position, as shownin Fig. 1, all strains which are exerted upon the checkrein, and throughit upon the hook A, are prevented from withdrawing the hook B from theshoulder A of the rear portion of the hook A.

When it is desired to withdraw the check= rein from the hook A, it isfirst necessary to raise the bridge B. To do this, the latch 0 must bethrown backward from over the hook 13 It is to accomplish this with easethat I have provided the handle C for the latch O, which handle extendsfrom the opposite end of the pivot or pin 0 from that occupied by theoperative end of the latch. This construction facilitates the operationof opening the hook A, for the reason that the direction of the pull onthe handle 0 and the bridge B are in practically the same direction. Thethumb being placed behind the handle 0 and the end of the forefingerplaced under bridge B, the pull exerted by the thumb upon the handle 0is in a forward direction, the same direction to which the bridge B isto be carried. The latch 0 being thrown into unlocking position, thebridge 13 is raised into the position shown in Fig. 2 and the cheekreinslipped upward out of the hook A and over the bridge B, releasing thecheckrein without necessitating the backward draw of the same, which hasheretofore been necessary by reason of the rearward extension of theentrance to the checkrein-hook.

The checkrein-hook herein described is' above said hook when the sameengages said raised shoulder; substantially as described. In testimonywhereof I have hereunto set my hand this 17th day of June, 1899.
